To solve this, the first thing we need to do is to take the data from the table and create an ordered ascending list:
28, 30, 31, 31, 33, 38, 40, 41, 41, 44, 45, 46, 49, 50, 53, 54, 57, 59, 59, 60
To find the mean, we need to add all these values and divide by the total, 20:
To find the median, we need to look at the value that falls in the middle of the list. In this case, the list has an even number of elements, thus it will be 2 numbers in the middle of the list: 44 and 45. To find the median, we calculate the mean between these values:
The mode is the number that repeats the most. In this case, there are 3 values that repeat 2 times each: 31, 41, and 59.
Then:
Mean: 44.45
Median: 44.5
Mode: 31, 41, 59
